An email (and text message) notification is sent to you anytime you or someone else unsuccessfully tries to log in to your user account. One of the first things we do to protect your account is to notify you right away if someone tries and fails to log in to your user account. If this happens, you'll receive a notification that looks like this:
​
Subject: WARNING: Failed Login Attempt
​

First, you need to determine if this was you. If this was you, then you don't need to do anything. If you don't know your correct username and/or password, you can reset it from https://horizonwebref.com/forgot
​
If this wasn't you, you don't need to panic, but you should take action. Many cases are relatively innocent mistakes in which another user with a similar username may have accidentally tried to use your username. However, it is possible that someone was maliciously trying to gain access to your account. In either case, you should immediately check to see if you still have access to your account by logging in at http://my.horizonwebref.com. If you cannot log in, you should immediately reset your password at https://horizonwebref.com/forgot
​
Once you log in, you should change your username to prevent any further failed login attempts. You can (optionally) change your password, too. You can do this by going to Administrative Forms >> Change Username/Password.
​
Remember NEVER to give your username or password to ANYONE. That includes your scheduler, friends, family, other officials, technical support staff, your pet parrot, etc. You can see this support article for help with creating a secure password.
​
The Horizon technical support staff will never ask you for your username or your password, and we will definitely never ask you for your username and password in an email notification. If you receive security notifications from us, you should always open a new browser window and manually type http://my.horizonwebref.com into your web browser's URL address bar to ensure you're visiting a genuine Horizon login page.
